Time travel is tricky. Will you destroy your present by going back in time and changing something? But what if your present is dictated by what you did when you went back in time? Paradoxes are fun. While you try to figure out why the plot of Terminator shouldn't work, save some dough on a time-altering game, favorite your friends with icons, and control your computer on the go with today's app deals.

I really wanted Apple to release Back to My Mac for iOS. Of course, they never listen to me. Fortunately, you can peep your Mac and PC with Splashtop Remote for a few bucks. The app streams video and audio. You could potentially watch a video on your iPad that's playing on your computer at home. So that's kinda cool. Dropped from $5 to $3. [AppShopper]

Creating an icon that's a shortcut to contact your friend is genius. You probably have hundreds of contacts in your address book, but I'm sure only about 10 of them are actually important. iFavorite Pro will create an icon for those lucky few for quick access to texting, calling, Facetiming, emailing, or their website. Seriously, someone give these guys a medal. Dropped from $3 to Free. [Apps-aholic]

Ducks that can control time. That's really all I should have to say to make you download this app. If you're still not convinced, it's a cross between Frogger and Braid. You draw a path for animals to cross a busy street. If things get to hairy, the animals can rewind and fast forward time to create an opening. Did I mention it has ducks? Dropped from $2 to $1.

I don't understand fishing games. The appeal of fishing is being outside while attempting to scam a fish into eating your lure. This app has the words "fantasy" and "funny" in it. So I figured, "What the hell?" I hope you fish-game-loving folks enjoy it. Dropped from $2.50 to $1. [Apps-aholic]
